Abstract

A GaAs pseudo-heterojunction bipolar transistor with a heavily carbon-doped base grown by metalorganic molecular beam epitaxy was fabricated, and the highest dc current gain of 1.7 was obtained, which evidences band-gap narrowing in the base. However, hole injection from the base to the emitter still cannot be ignored, and the use of a heavily carbon-doped InGaAs base is proposed to improve transistor characteristics.
